I am about to install Smart Solar 100/20, replacing my not-working CTEK D250SA. I read the manual and saw that there is an error code 2 that will appear if the battery voltage is higher than set. I still want to utilize my other means of charging: AC-DC charger when I am camping ( was connected to leisure battery directly by now) and , and my Car alternator (was connected to the CTEK D250SA alternator port). I want to connect them both to the leisure battery directly, now. However I understand that the voltage rise when charging with any of them will cause Error 2 on the Smart Solar MPPT device. The manual says that this will automatically reset, when the voltage goes back to normal. My questions are:
1. Am I assuming correctly?
2. Is my intended setup safe for the controller?
3. If 2=false what should I do as a workaround?
